Gentoo Linux Security Advisory

Title: libxml2: Denial of Service (GLSA 201203-04)
Severity: normal
Exploitable: remote
Date: March 06, 2012
Bug(s): #405261
ID: 201203-04

Synopsis

A hash collision vulnerability in libxml2 allows remote attackers
to cause a Denial of Service condition.


Background

libxml2 is the XML C parser and toolkit developed for the Gnome project.

Affected Packages

Package: dev-libs/libxml2
Vulnerable: < 2.7.8-r5
Unaffected: >= 2.7.8-r5
Architectures: All supported architectures


Description

libxml2 does not properly randomize hash functions to protect against
hash collision attacks.


Impact

A remote attacker could entice a user or automated system to open a
specially crafted XML document with an application using libxml2
resulting in a Denial of Service condition.


Workaround

There is no known workaround at this time.

Resolution

All libxml2 users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r5"
